The world is still reflecting on how Debbie Reynolds And Carrie Fisher were one of the greatest celebrity mother-daughter pairs in Hollywood before their deaths less than 24 hours apart from each other in December. But they are by no means the only super family duo that the celebrity has had to offer.

Liza Minnelli has been admitted into rehab but is progressing well. Here are five things you need to know about the 69-year-old entertainer.

Liza Minnelli has recently been admitted into rehab so she can get help with substance abuse problems. The 69-year-old reportedly checked herself in early this week and is already showing signs of "excellent progress". Just in case you're struggling with the Minnelli trivia, here are five things you need to know about the Cabaret actress:

The veteran entertainer is said to have checked herself into a treatment facility days ago.

Liza Minnelli is said to be making "excellent progress” at an undisclosed rehab facility, according to a spokesperson for the singer and actress. The 69 year old checked herself into rehab for the treatment of substance abuse, her spokesperson confirmed yesterday, while TMZ reports that alcohol is the main issue Minnelli is currently being treated for.

"Liza Minnelli has valiantly battled substance abuse over the years and whenever she has needed to seek treatment she has done so," spokesperson Scott Gorenstein said in a statement. Adding that the actress was “currently making excellent progress at an undisclosed facility.”

Veteren star Liza Minnelli has thanked her fans for their support and thoughts whilst undergoing back surgery. The star was injured in a fall and had undergone surgery to try and repair this.

A statement from the 68 year old star of films including Cabaret and The Sterile Cuckoo reads "I am overwhelmed with the amount of love and caring that has been sent my way from all over the world." Minnelli revealed that following a tumble at her home she was left unable to walk, and had to miss many engagements this year, as well as the funeral of her longtime friend Joan Rivers as she was preparing for surgery in California.

Liza Minnelli's concert at the Royal Albert Hall in July has been cancelled due to the singer's ill health. A statement was released on her website earlier this month explaining how, on doctors' orders, she has been advised not to travel or perform.

Liza Minnelli has been forced to cancel a number of concerts over the summer on her doctors' orders. The 68-year-old is suffering from an undisclosed illness and has been told not to perform or travel.

Minnelli, who is the daughter of the late actress Judy Garland, has been suffering from ill health of late. She has recently undergone two hip replacements. However, the illness which has caused her to cancel her upcoming appearances is yet to be revealed.

Liza Minnelli didn't have exactly the best time at last night's Oscars. As one of Hollywood's biggest veteran stars, the actress didn't receive the respect that a performer of her calibre would deserve. From being the target of a mean zing from Ellen Degeneres, to having her outfit mocked in the media and being laughed at for not being able to reach into the famous 'Oscars Selfie' in time, Liza could have had a nicer evening at home.

The glamorous awards evening started on the red carpet where Liza, the daughter of Judy Garland, debuted a striking new streak of blue in her black hair and wore a matching silky pantsuit with dramatic diamond jewellery. As the snaps of Minnelli hit the internet, commenters began to point out and mock the fact that the actress probably wasn't wearing a bra under her slinky suit.

A thrice broken wrist was overlooked for Minnelli to take to the stage with her half-sister, Lorna Luft.

Liza Minnelli bravely ignored the pain of a broken wrist to perform at New York City's famed Birdland jazz club to benefit The Actors Fund's Phyllis Newman Women's Health Initiative and Tower Cancer Research Foundation's Dr. Philomena McAndrew Fund.

The 67 year-old performer's rep told the Associated Press that Minnelli had broken her wrist in three places as she rehearsed for the show on Sunday night and that her doctor had advised the Academy Award winner not to perform. However, the cause was so close to Liza's heart that she felt she couldn't possibly back out when her half-sister Lorna Luft, who is battling breast cancer, had asked for a little help making the evening as special as possible.

Last night (April 22, 2013), Barbra Streisand was the centre of attention at the Lincoln Center in New York. The 70 year old actress, singer, and filmmaker received the Film Society of Lincoln Center’s 40th annual Chaplin award, CBC News reports. Throughout the evening, tribute was paid to the star, with a variety of musical lumanaries taking to the stage to praise her work, or sending in video messages that were played to those gathered for the glitzy event.

“Ever since I can remember, people have been calling me bossy and opinionated," Streisand said, accepting the award. “Maybe that's because I am. Three cheers for bossy women!" she declared, sparking roars from the star-studded audience. Streisand has won Oscar awards, Tony awards and Emmys for various aspects of her work but last night was solely focused on the entirety of her show-business career. “Thank God I was given a good voice,” she joked.

Paying tribute to the star were the jazz trumpeter Wynton Marsalis, along with singers Liza Minnelli and Tony Bennett. Her former movie co-stars, Omar Sharif, Blythe Danner, Ben Stiller and Robert Redford all chipped in with warm words about the actress. Even President Bill Clinton had a thing or two to say: “Every great person is driven," friend and former U.S. president Bill Clinton said onstage. But if that person has massive talent, big brains and a bigger heart, you want to go along for the ride."

The Broadway veteran didn’t just have a party like any old celebrity, she marked the occasion with a special one-off performance alongside another staple of the Big White Way, Alan Cumming. The pair performed a number of famous duets on Wednesday, before dashing off to celebrate elsewhere. The show, which was just the first of a pair of gigs at NY Town Hall, reprised Liza and Alan’s cabaret-like performance at a Fire Island nightclub last summer.

Of course, the infamous Cabaret was performed (making us musical theatre fans extremely jealous of the ticket holders) and the entire show turned into a Cabaret reunion of sorts. But this time, the roles were reversed, as Cumming took on Liza’s part in Mein Herr, which is one of the best-known numbers Sally Bowles (Liza Minnelli) performs in the original musical, while she herself sang the traditionally male Willkommen. Overall, the night was a lot of fun for both fans and performers. "We're just crazy about each other," Minnelli told Reuters after the show. "It felt very intimate, like being with a bunch of friends." After the intimate performance, Liza managed to out-party any of her younger colleagues, alongside a group of close friends at New York’s Copacabana.
